In this study, the properties of polypropylene (iPP) were studied, and the influence of high-density polyethylene-polypropylene block copolymer (HIPPPOE) on the toughening of iPP and its mechanism were explored by binary blending. The results showed that adding HIPPPOE can significantly improve the toughness and impact resistance of iPP, and the toughening effect gradually increases with the increase of HIPPPOE content. At the same time, it was found through scanning electron microscopy (SEM) observation that the morphology of iPP changed into a more regular and compact morphology after adding HIPPPOE, which may be one of the toughening mechanisms. This study provides a new idea for exploring the toughening mechanism of plastics, and provides an important research foundation for the development and application of plastic products.【Keywords】 HIPPPOE; iPP; binary blending; toughening; scanning electron microscopy
